Reconnect the plug on the Air Flow Meter, I guess.

Seems like letting it sit overnight would natually un-flood it, no?
I tested both the resistance of the Temp II sensor and it's wiring: all
good.
I tested the fuel pressure: 30 psi while cranking, so that's not the issue.
I guess I'll just start troubleshooting from square one tomorrow....
